Males and females often differ in their susceptibility and exposure to infection. Thus, they may also differ in their ability to avoid infection. The beetle, Tenebrio molitor, risks infection with cysticercoids when ingesting rat feces containing eggs of the tapeworm, Hymenolepis diminuta. Previous studies demonstrated that beetles sometimes prefer infective feces suggesting that the tapeworm i...

Cocconeis diminuta, a marine benthic diatom, metabolizes acetate and lactate-(14)C. In the light, the major product was lipid, whereas in the dark, CO(2) was the major product. Analysis of proteins synthesized in the presence of acetate or lactate showed that radioactivity was incorporated predominantly into the glutamate family of amino acids and those amino acids related directly to the subst...

A new species of Notoschoenomyza Malloch, N. diminuta sp. nov. from Chile, is described and the male and female terminalia are illustrated. A key to the identification of all Notoschoenomyza species is presented.

In 1986, we encountered the first case of Legionella micdadei pneumonia in Japan. In the follow-up study to determine the infection route of L. micdadei, we isolated Brevundimonas vesicularis from the shower hose of the patient�s home. This motivated us to explore the symbiosis between B. vesicularis and Legionella in this study. B. vesicularis type strain, B. vesicularis Kobe strain, Legionell...

Dear Editor, The genus Flavobacterium is the type genus of the family Flavobacteriaceae, which currently comprises more than 25 other genera, whose members are widely distributed in nature [1]. F. ceti sp. nov., a gram-negative bacillus, was isolated from beaked whales (Ziphius cavirostris) found along the coast of the Canary Islands, Spain in 2007 [2]. This microorganism does not form spores a...

An adult hymenolepidid tapeworm was recovered from a 52-year-old Tibetan woman during a routine epidemiological survey for human taeniasis/cysticercosis in Sichuan, China. Phylogenetic analyses based on sequences of nuclear 28S ribosomal DNA and mitochondrial cytochrome c oxidase subunit 1 showed that the human isolate is distinct from Hymenolepis diminuta and Hymenolepis nana, the common paras...

The anaerobic incorporation of 32P into ATP by the tapeworm Hymenolepis diminuta was studied in the presence and absence of uncouplers of oxidative phosphorylation and anticestodal agents. Low concentrations of all compounds tested inhibited this incorporation. Under the anaerobic conditions employed, internal ATP concentrations remained constant in spite of the inhibition of the incorporation ...

The rapid elimination of the intestinal phase of Trichinella spiralis in NIH mice is associated with progressive inflammation of the intestinal tract. The non-specific effects of this inflammation were studied in mice concurrently infected with an unrelated parasite, Hymenolepis diminuta, which does not stimulate a visible inflammatory response but is also immunologically rejected by this strai...
